UndirectedSubgraph
public UndirectedSubgraph(UndirectedGraph<V,E> base, java.util.Set<V> vertexSubset, java.util.Set<E> edgeSubset)
Creates a new undirected subgraph.- Parameters:
base
- the base (backing) graph on which the subgraph will be based.vertexSubset
- vertices to include in the subgraph. Ifnull
then all vertices are included.edgeSubset
- edges to in include in the subgraph. Ifnull
then all the edges whose vertices found in the graph are included.

degreeOf
public int degreeOf(V vertex)
Description copied from interface:UndirectedGraph
Returns the degree of the specified vertex. A degree of a vertex in an undirected graph is the number of edges touching that vertex.- Specified by:
degreeOf
in interfaceUndirectedGraph<V,E>
- Parameters:
vertex
- vertex whose degree is to be calculated.- Returns:
- the degree of the specified vertex.
